Purpose:
The Purpose was to calculate the frequencies of alleles and genotypes in the gene pool of a population using the Hardy-Weinberg formula and discuss natural selection and other causes of micro evolution as deviations from the conditions required to maintain Hardy-Weinberg equilibrium.
Summary/Data:
Hardy-Weinberg = p^2 + 2pq +q^2 = 1
population allele and genotype will remain constant from generation to generation under the following conditions:
1.The breeding population is large
2. Mating is random
3. There is no mutation of alleles
4. No differential migration occurs
5. There is no selection
The class simulated a population of random mating heterozygous individuals with an initial gene frequency of .5 for the dominate allele A and the recessive allele a and genotype frequencies of .25 AA, .5 Aa, and .25 aa. Your initial genotype id Aa. each student receive four cards, and these cards represented the genotype of the students, and traded these cards to simulate mating.
Conclusion:
Our data showed that heterozygous pairs are the most frequent, aa were eventually eliminated and AA was the most common after several generations. However our mating didn't strictly follow the Hardy-Weinberg conditions.
The purpose of the lab was to understand genetic variation through generations in a small population. After each generation, genotypes were written down. Frequencies were determined based on genotypes of the population, and in a small population there is not was much variation. As certain genotypes were eliminated (like homozygous recessive) variation decreased even more.
